low energy light bulbs - a comparison of cfls and leds light bulbs
The government tends to use energy-efficient bulbs, such as compact fluorescent lamps (CFLs)
Both products are used in homes across the United States, but the cfl is used for the longest time.
There are several advantages and disadvantages to using these technologies.
Let\'s consider here: the average life of a compact fluorescent bulb is 10 times longer than that of an incandescent lamp.
The Energy Star rated CFLs uses less energy, about 75%, saving $30 over the lifetime of a single bulb.
However, CFLs take longer than incandescent lamps to warm up and produce cooler light.
Manufacturers respond to customers complaining about the low quality of CFLs lighting by developing a new generation of incandescent-like lamps.
In terms of lighting, the CFLs closest to incandescent lamps fall between 2700 and 3000 on the Kelvin scale.
In contrast to the yellow tone of incandescent lamps, the CFL bulb that produces natural daylight tones belongs to 5000-
6500 on Kelvin scale and 3500-
4100 light is colder and whiter. (
The number of Kelvin scales is on the package. )
A major drawback to using CFLs is that each bulb contains mercury.
If the bulb is broken, if you throw it away incorrectly, it can be harmful to everyone at home.
Cleaning up a broken bulb sometimes requires hiring an expert in hazardous materials, which can cost up to thousands of dollars.

The Watt-energy-saving lamp is $ Month, and the monthly work is $. 67 per bulb.
This is equivalent to a 100-
Incandescent lamps in Watt.
General Electric 100-

CFLs costs more but saves energy.
However, CFL users expect products with lower prices.
Advantages and disadvantages of LEDsLEDS using less wattage (2-10 watts)
Not too much heat.
They can be used for 4.
5 years in a row before \"death\", equivalent to 40,000 hours.
Unlike CFLS, the led does not contain mercury, which is a huge advantage.
They don\'t have any filaments, so there\'s no chemical hazard if they break.
Led has disadvantages.
One is that they are only useful for downlighting or task lighting.
They don\'t shine to the bottom of the bulb, and the brightest available is only 60-
Incandescent lamps in Watt.
The Led looks darker because the temperature of the lamp is lower than that of incandescent lamps and CFLs.
However, they are more useful as night lights, as they emit shades of blue.
You can also use them for accent lighting.
New technologies are being developed to address the disadvantages of using LEDs.
For example, Sharp\'s LED series (a nine-bulb LED)
It is equipped with a remote control that allows the user to change the tone of the light.
However, the led is still expensive, the price of sharp is $82, the price of ordinary led is about $35.
When the price of these bulbs drops, it may end up being more cost-effective than CFLs and incandescent lamps.
LEDs use less than $50 in electricity in 4 to 5 years, and will eventually surpass both.
